Title: Cooling method of blast furnace body
Inventor: FUNABASHI KAZUTOMI
IPC: C21B7/10
Filed: 1982-06-07
Abstract: PURPOSE:To improve the cooling efficiency of a furnace body and the deaeration efficiency of quasi-pure water by subjecting the pure water from a deaerator to heat exchanging with the quasi-pure water from a service tank, cooling the pure water further in a cooler, and supplying the same to a steam drum thereby cooling the furnace body. CONSTITUTION:The quasi-pure water from a service tank 1 is fed by a pump 4 to a deaerator 2 where the water is sprayed and is then heated and deaerated by the heating steam 5 blown thereto. The dehydrated pure water of a high temp. is fed from the deaerator 2 to a heat exchanger 10 where the water is subjected to the heat exchanging with the quasi-pure water of a low temp. from the tank 1 so that the pure water of a high temp. is cooled and the quasi-pure water of a low temp. is heated. The deaeration efficiency of the quasi-pure water in the deaerator 2 is thus improved. The cooled pure water is cooled further by a cooler 11 by sea water ot the like, and the cooled water is supplied to a steam drum 8, from which the water is circulated to a furnace body cooler 3 to improve the cooling efficiency of the cooler 3.

Title: Consecutive photographing camera
Inventor: KONO KOJI
IPC: G03B15/16
Filed: 1995-04-21
Abstract: PURPOSE: To make a consecutive photographing camera low in cost and compact in size by adopting a freely ascendable and descendable connecting plate as a mechanism for connecting a shutter charging mechanism and a film wind stopping mechanism by a shutter release. CONSTITUTION: The connecting plate 72 moves to an ascent position to hold a traveling plate 48 in a charging position when the traveling plate 48 returns to the charging position while being linked with film winding operation, and moves to a descent position while being linked with the shutter release to release the holding of the traveling plate 48 in the charging position. When a wind stopping lever 74 turns to a wind-stop releasing position while being linked with the movement to the descent position of the connecting plate 72, the wind stopping lever 74 retreats a wind stopping pawl 74c from a winding knob 28 to permit the winding operation of the film. Moreover, when the lever 74 turns toward a wind stopping position while being linked with the movement to the ascending position of the connecting plate 72 and the photographic film 23 of one picture frame is moved, the wind stopping pawl 74c is engaged with the winding knob 28 to inhibit the film winding operation.

Title: Method for observing surface form
Inventor: TAKASU MASAO
IPC: H01J37/28
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To observe a surface form without distortion by correcting the signal quantity of reflected electron or secondary electron on the basis of a calculated angle slippage. SOLUTION: An error angle can be determined when two conditions of measurement magnification [values of (x), (y)] and the distance [value (z)] from a scanning coil to a sample surface are set. Thus, the error angle portion obtained by calculation is corrected with respect to the information (angle including error) of form obtained by two-dimensional scanning, whereby a precise form can be provided in all positions within the scanning area. The inclining direction of the angle error in all positions except the center of the scanning area is the direction directing from the center to the measuring point. Thus, the true inclination is obtained by the measured inclination + the calculated error angle.  This correction can be performed by either one method of correcting the irregularity information calculated as the three-dimensional form directly as an angle value, and correcting the electron signal intensity before it is made into the irregularity information.

IPC: G11B7/20
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To provide an optical head and an optical memory device which can reproduce a high density optical recording medium of the next generation while keeping interchangeability for an optical recording medium of a write-once type of the existing pigment system. SOLUTION: A main lobe 203 is made not to receive outside light by two light shielding sections; 201, 202. A center part of the main lobe 203 and major part of a side lobe 204 receive light and contribute to reproduction of a signal. The direction 205 of short sides of two light shading sections 201, 202 is substantially defined as the direction of arrangement of data pits of an optical recording medium. Since a side lobe part includes information of many shortest bits in a converged part of light returned from the optical recording medium, and the outside part of the main lobe includes many harmful components such as waveform interference, track interference or the like, characteristics are improved in this way.

Filed: 1979-07-31
Abstract: PURPOSE: To effectively control position in an axial direction of an axial side end surface of a frange part by balancing the thrusting force and the elastic force which is worked resisting the thrusting force at the grinding process.  
     CONSTITUTION: A workpiece 1 is moved by the thrusting force P at the grinding and the elastic supporting member 5 bends at an axial side end surface 1b, so that the elastic force P2 resisting the thrusting force P works upon the workpiece 1. As the bending of the elastic supporting member 5 increases and the distance S between the axial side end surface 1b of the workpiece 1 and an abrasive wheel 3 becomes zero to start grinding the end surface 1b with the wheel 3, the grinding resistance P1 adds up the elastic force P2 to resist the thrusting force P. By balacing the resultant force of the grinding resistance P1 and the elastic force P2, the position of the workpiece 1 in the axial direction during grinding can be controlled, and the grinding accurace of the shaft part end surface 1b can be made uniform.
